How to fix code p1745 transmission line pressure too high on a dodge pick up 2008

Interesting new code to me. Line pressure.

..

P1745 Description The P1745 code is an informational code to inform the technician that transmission has been operating in an open-loop line pressure control for 3220 kilometers (2000 miles) or 1000 2-3 upshifts resulting from a Line Pressure DTC. The Transmission is not designed to operate in open-loop line pressure control for an extended period time. This code is intended to protect the transmission. If the P1745 code sets, the transmission controller will place the transmission into limp-in mode.

Send it for transmission repairs/service.

The lines should be routed the way they originally were. If they are too long or the psi is too high you may have a hard bends in the line where it doesn't belong, The lines not have any sharp bends in them that will slow down pressure. Long/ gentle bends along the tube is what it needs,

It's the Pressure Control Solenoid and if you get that code erased it should shift again.
At a stand still it reduces pressure you don't have to replace it just erase the code.
You may see a drop little in mpg
Hope it helps

Sounds like the filter screen in the transmission has become clogged.

code p0935 refers to hydraulic pressure sensor--circuit high input===causes --wiring--short to positive--hydraulic pressure sensor--ECM/TCM--TCM -transmission control module.
. Have a pressure test done on the box to ensure that the pressure is correct and that there are no internal issues. Most issues concern the TCM

P0963 "Pressure Control Solenoid A Circuit High (Line Pressure Solenoid)". Check for opens and high resistance.
P1729 "Transmission Ratio Control Circuit (Stepper Motor). Invalid Electric Voltages.

The code for this concern is related to the EPC solenoid in the transaxle.

P1745 EPC EPC solenoid circuit failure EPC solenoid, circuit or PCM shorted or open. Soft/harsh shift feel

The wire to the EPC solenoid is a yellow and violet wire.The code indicates that the problem is strictly caused by this solenoid circuit. I would suggest inspecting this wire from the trans to the PCM.If there are no obvious faults, replace the wire with a new wire ,eliminating the faulty circuit. Hope this helped you.

p1643- fuel pump monitor circuit low input / p1745- line pressure solenoid system. this is starting to sound like a ecu issue. i would verify fuel pressure and double check your fuel filter. start there.
